In this step we create two div that holds the image and content,each width is 700px and.Then we use css background property to apply images in divs background and make them fixed to get parallax effect.Then we use $(window).scroll function to run the function when user scrolls the window and under this function we get how much distance the user scroll the page.You may also like Load Results From Database On Page Scroll Using jQuery,Ajax And PHP
And then we divide the number by 6 it is the speed to which the background image scroll you can specify any number in place of 6 and also we use (-) sign because to create parallax effect you have to move the image opposite to the scrolling direction and by using negative sign when the user scroll down image moves upward and when scroll up image moves down.
We use 100 in if condition because we need to show parallax after 100px distance from top you can specify any number as you wish.You may also like animated background using CSS3.
